• European Commission grants conditional marketing authorization based on the EFFISAYIL® 1 trial, which demonstrated that over half of the spesolimab-treated patients were free of pustules, one week after receiving a single dose
  • Generalized pustular psoriasis (GPP) differs significantly from plaque psoriasis in both its disease mechanism and severity

United Arab Emirates, Dubai – The European Commission (EC) granted a conditional marketing authorization for Boehringer Ingelheim’s spesolimab as first in class treatment for GPP flares in adults.1 Spesolimab is a novel, selective antibody that blocks the activation of the interleukin-36 receptor (IL-36R), a signaling pathway within the immune system shown to be involved in the pathogenesis of GPP.2, 4-7

Mohammed Al-Tawil, Regional Managing Director, and Head of Human Pharma at Boehringer Ingelheim, India, the Middle East, Turkey, and Africa region, said, "The approval of spesolimab for GPP patients marked a major milestone in Boehringer Ingelheim's clinical development program. Until now, people living with GPP had limited treatment options that could help them manage their flare incidents. This important approval can help us raise awareness about this rare skin condition and bring innovative treatments faster to those most in need. We will continue to explore the utility of spesolimab in a variety of neutrophilic skin diseases through further clinical trials, with the goal of transforming the lives of people for generations to come."

“The symptoms of GPP are devastating and cause immense pain as well as hospitalization during a flare. Increased GPP awareness that leads to accurate and faster diagnosis is one important step to improving the quality of life for people living with GPP,” said Frida Dunger Johnsson, Executive Director, IFPA. “Now with a specifically developed treatment, people living with GPP can be offered a new lease of life by effectively managing the impact of GPP flares.”

The EC’s conditional approval of spesolimab is based on results from the pivotal EFFISAYIL® 1 Phase II clinical trial.2 In the 12-week trial, patients experiencing a GPP flare were treated with spesolimab or placebo. Most patients at the outset of the trial had a moderate or severe pustulation of the skin. After one week, 54% of patients treated with a single dose of spesolimab showed no visible pustules compared to placebo (6%).2 Adverse events were reported in 66% of patients treated with spesolimab and 56% of those receiving placebo after one week.2 Infections were reported by 17% and 6% of patients in the spesolimab and placebo groups respectively (at week one).2 Serious adverse events were reported in 6% of patients treated with spesolimab (at week one).2

People living with GPP often do not receive a correct or timely diagnosis and may have their symptoms identified as other forms of psoriasis. A Global Delphi Consensus Project classified GPP as phenotypically, genetically, immunologically and histopathologically distinct from psoriasis vulgaris / plaque psoriasis based on a systematic literature review.3 The growing list of regulatory approvals for spesolimab for the treatment of GPP flares underlines that the Delphi panel’s vision of improved diagnosis and treatment for people with GPP is increasingly achievable.

About the EFFISAYIL® 1 clinical trial1

EFFISAYIL® 1 (NCT03782792) was a 12-week, Phase II trial investigating patients with a GPP flare (N=53), randomly assigned 2:1 to a single 900 mg intravenous dose of spesolimab or placebo.2

After one week, 54% of patients treated with spesolimab showed no visible pustules, compared to 6% of patients treated with placebo.2

After 12 weeks more than 4 out of 5 patients (84.4%) had no visible pustules and clear/almost clear skin (81.3%).10

Adverse events were reported in 66% of patients treated with spesolimab and 56% of those receiving placebo after one week. Infections were reported by 17% and 6% of patients in the spesolimab and placebo groups respectively (at week one). Serious adverse events were reported in 6% of patients treated with spesolimab (at week one).2

About generalized pustular psoriasis (GPP)

GPP is a rare, heterogenous and potentially life-threatening neutrophilic skin disease, which is clinically distinct from plaque psoriasis.4, 11 GPP is caused by neutrophils (a type of white blood cell) accumulating in the skin, resulting in painful, sterile pustules all over the body.4, 11 The clinical course varies, with some patients having a relapsing disease with recurrent flares, and others having a persistent disease with intermittent flares.11 While the severity of GPP flares can vary, if left untreated they can be life-threatening due to complications such as sepsis and multisystem organ failure.4 This chronic, systemic disease has a substantial quality of life impact for patients and places an increased burden on healthcare systems.12 GPP has a varied prevalence across different geographical regions and more women are affected than men.4, 12-14 There is a high unmet need for treatments with an acceptable safety profile that can rapidly resolve the symptoms of GPP flares and prevent their reoccurrence.3

GPP flares can lead to hospitalization with serious complications, including heart failure, renal failure and sepsis, with the unpredictability and severity of these flares greatly affecting a person’s quality of life.4
